Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27904, here are decompositions:

  • 3 + 27901 = 27904
  • 11 + 27893 = 27904
  • 53 + 27851 = 27904
  • 101 + 27803 = 27904
  • 113 + 27791 = 27904
  • 131 + 27773 = 27904
  • 137 + 27767 = 27904
  • 167 + 27737 = 27904

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27904 first appears in π at position 47,304 of the decimal expansion (the 47,304ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
